need a master fader for Tascam M35

[electrocutioner]

Does anyone know where can I find one? It's an Alps 10KA x4 (quadruple) 88mm.

Unfortunately one of the tracks is broken and buss 3 is always at maximum.

Does anyone have the service manual?

I found an Alps 100KAx4 but I don't have the schematic to check how a larger value fader will affect the circuit. Is the master fader in parallel with the submaster faders? In this case, it'll be better if it's a larger value.

Is this a slide type fader or rotary? I did as search for Alps 100KAx4 and am finding motorized rotary(?)

I got a feeling that ALPS 88mm throw could have been a proprietary build for Tascam. Can you live with a shorter throw 60mm?

or maybe..

Or perhaps it is the correct one(?)....

Thanks for the links!

It's a slide type like the links you posted on eBay, 60mm travel (88mmx24mm). They are the same pots I have found.

The only problem is that the original is 10K Audio (log) and the seller has 10K Linear or 100K Audio. That's why I'm asking how the 100K will affect the circuit. I prefer to use audio than linear.
